Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed July 29, 1907. Serial No. 386087.

.To all whom it may concern:

Be it known that I, FREDERICK M. BEOKET, asubject of the King of- Great Britain, residing at .Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Process of Reducing Metallic bulfids and Producing Vanadium, of which the following is as ecification n the roduction of metals and alloys, for exam e vanadium or ferro-vanadium, from su d ores, it is customary to first roast the sulfid to an oxid and to then. subject the roasted product or a concentrate therefrom to the action of a reducing agent.

According to the present process sulfid ores of vanadium and other metals are ivms ysio av s1s,+ es

Various intermediate and subsidiary reactions may take place and the process is not limited to the recise reaction or reacting pro ortions indicated in the equation.

he materials constituting the charge are mixed and heated to the requisite temperature, preferably in an electric furnace. By using a closed furnace and maintaining nonoxidizing conditions, both the silicon and carbon disulfids may be collected. Or these products maybe burned with ai to recover the sulfur contents as sulfur dioxid.

In the production of alloys of the vanadium or other reduced metal with iron, nickel or other metal, the alloying metal may be directly added to the char e or may bereduced from its compound ad ed to the charge, simultaneousl with the reduction ofthe metal of thesu fid.

-By this process vanadium or vanadium alloys containing a very low percentage of carbon-and merel a trace of sulfur may be producedfrom'su fid ores in a single operation by the use of a relatively cheap reducing a ent.

, I 0 mm:

1. The process of reducing metallic sulfids, which-consists in smelting a chargeicontaim ing the sulfid, and a reducing agent comprising silicon and carbon.

2. The process of reducing metallic sulfids, Which consists in smelting a charge containing the sulfid and a compound of silicon. and carbon. y 3. The process of reducing metallic sulfids, which consists in smelting a charge containing the sulfid and carborundum.

4. 'The process of producing alloys, which consists in smelting a charge containing a sulfid of one of the alloying metals, silicon, carbon, and a source of the other alloying metal.

5. The process of producing alloys, which consists in smelting a charge containing a sulfid of one of the alloying metals, a com pound of silicon and carbon, and a source of the other alloying metal.

6. The process of producing alloys, which consists in smelting a charge containin a sulfid of one of the alloying metals, car borundum, and a source of the other alloying metal.

7. The process of reducing vanadium sul fid. which consists in smelting a charge containing the sulfid, silicon and carbon.

8. The process of reducing vanadium sulfid, which consists in smelting a charge con taining the sulfid and a compound of silicon and carbon.

9. The process of reducing vanadium sulfid, which consists in smelting a charge containing the sulfid and carborundum.

10. The rocess of roducing vanadium alloys, whic 1 consists 1n smelting a charge containing vanadium sulfid, silicon, carbon, and a source of the alloying metal.

' 11. The process of producing vanadium alloys, which consists in smelting a charge containing vanadium sulfid,a com ound of silicon and carbon, and a source of t 1e alloying metal.

12. The process of roducing vanadium alloys, which consists in, smelting a charge containing vanadium sulfid, carborundum. and a source of the alloying metal.

In testimony whereof, I am my signature in presence of two witnesses.

FREDERICK M. BECKET.
